SELF-WINDING SUSPENSTON DEVICE.

Specification of Letters Patent.

Patented Jan. 20,1914.

Application filed March 17, 1913. Serial No. 754,672.

To all whom it may concern:

Be it known that I, JAMES V. Gnnovnsn, a citizen of the United States,residing at Brewster, Putnam county, New York, have invented certain newand useful Improvements in Self-Winding Suspension Devices, of which thefollowing is a full, clear, and exact description.

My invention relates to a new and improved self-winding suspensiondevice which may be used to particular advantage for suspending sucharticles as chalk used for chalking the tips of billiard cues.

The object of the invention is to produce a very simple device of thischaracter which may be easily manufactured and easily repaired withoutthe exercise of any special skill.

In the drawings Figure 1 is a side elevation of my invention, the casebeing shown in section. Fig. 2 is a plan view thereof, the upper sectionof the case being removed. Fig. 3 is an end view of a detail. Fig. l isa view of detached details.

12 represent two hollow preferably hemispherical cover parts which arearranged to be detachably interlocked by any well known locking means,for example the well known bayonet joint lock, the stud parts of whichare shown at 33 in Fig. 2; These studs are shown as carried by the lowercase section 2, in which event the interlocking slots (not seen) forcooperation therewith would be formed on the other section 1.

4 is a spool preferably having flanges 55. The spool 4 is also provided,by preference, with an axle 6, the ends of which are detachably mountedin brackets 78, which may be carried by the part 2 of the casing. Thebracket 7 at its upper end is offset from the casing to form a holdingshoulder or anchorage for the rubber hand later described. The upper endof said bracket? is likewise turned forwardly toward the spool 4, andthen downwardly, and is provided with a perforation 7 to receive theadjacent end of the shaft 6, the extreme end of the shaft bearing forend thrust against the solid part of the bracket behind said perforatedend. The bracket 8 is similarly constructed, excepting that in place ofproviding a perforation therein similar to 7 said bracket is providedwith a slot 8*, open at the top and into which the adjacent end of theshaft 6 may be dropped, the end of the shaft bearing against the solidpart of the bracket back of the slot.

9 is a rubber band which is arranged as shown in the drawings, the endsof the band being slipped over the holding shoulders or anchoragesformed by the offset parts of the brackets 78, the sides of the bandlying in receiving grooves or notches 10-11 in the spool 4 to formholding shoulders.

Q 12 is a cord, one end of which is attached in any suitable manner tosaid spool, the other end leading down through an opening in the bottomof the part 2 of the casing, which opening is preferably eyeleted orlined, as at 14:, to prevent the abrasion of the cord 12 as it runstherethrough.

15 is a device by which the parts may be suspended.

16 represents the article supported by the cord 12, which in thisinstance may conventionally represent a holder for a piece of chalk.

To assemble the parts, the rubber band 9 is first placed longitudinallyaround the drum resting in the receiving grooves 10 and 11, the cord 12is then secured to the drum and wound circumferentially around the samewith only so much unwound as it is desired to have project from thecase. The free end of the cord is then passed through the eyelet 14c inthe lower section 2 of the case. The drum is then put into place withthe axle 6 resting on the brackets 78. The exposed end of the rubberband is then stretched around the brackets 7 and 8, as best seen in Fig.2. The upper section 1 of the casing is then coupled to the lowersection 2 and the parts are ready for use. A downward pull on the cord12 revolves the drum 4, winding up the rubber band 9. When the free endof the cord 12 is released, the rubber band 9 unwinds, revolving thespool so as to rewind the cord 12. Should the rubber band or cord break,the various parts may be easily separated and a new part insertedwithout the use of tools or the exercise of special skill.

The entire apparatus may be very easily and cheaply constructed andpresents a handsome and finished appearance when in use. The brackets7-8 which afford holding shoulders or anchorages for the band may, ofcourse, be carried by either part of the case or housing, or, indeed, inany suitable manner. In some instances where only light work isrequired, the axle 6 may be omitted, the rubber band itself aflording asufficient support for the spool 4. I would also regard a light coiledspring as the equivalent, in a broad sense, of the rubber band, althoughthe latter possesses specific advantages such as compactness, cheapness,availability and noiselessness in operation. I shall therefore use theterm elastic band in the following claims as a term of suiiicientbreadth to cover the rubber band shown or any means substitutedtherefor.

lVhat I claim is:

1. In a self-Winding suspension device, a

revoluble spool, an elastic band stretched longitudinally around thesame, an anchorage for said band at each end of the spool butindependent thereof, holding shoulders at each end of the spool for saidband whereby when the spool is revolved the ends of the band will notshift on said spool.

2. In a self-winding suspension device, a revoluble spool, an elasticband stretched longitudinally around the same, an anchorage for saidband at each end of the spool but independent thereof, said spool havingholding shoulders for said band whereby when said spool is revolved theends of said band will not shift on said spool and an axle for saidspool with supports for said axle adjacent to the anchorages for saidband.

3. In a self-winding suspension device for a revoluble spool, an elasticband stretched longitudinally around the same, an anchorage for saidband at each end of the spool but independent thereof, said spool havingholding shoulders for said band whereby when said spool is revolved theends of said band Will be properly held on said spool, an axle for saidspool with supports for said axle adjacent to the anchorages for saidband, and a cover for said parts, said cover affording a support forsaid anchorages.
